Vmware Tools event viewer

I am getting this error several times per second

[ warning] [vmusr:vmusr] SimpleSock: Socket 516 closed by peer.

In my event viewer. I tried http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=2036350 to turn off logging but it didnt work. Has anyone ran across this before?

Yes, it's a bug, fixed in ESXi 5.1 U3 Patch.

I would recommend updating to the latest version of ESXi 5.1.

I am using ESXI 6.0 actually
Andrew Hancock (VMware vExpert / EE MVE^2)VMware and Virtualization ConsultantCommented:
have you updated VMware Tools in the VM, because the issues is with VMware Tools ?

So if you have a VM from ESXi 5.1 with older version of VMware Tools, this will cause the issue.

What build of VMware Tools do you have in the VM, and is it all VMs ?

We’d all like to think our company’s data is well protected, but when you ask IT professionals they admit the data probably is not as safe as it could be.

Actually I just happened to come across a thread on Vmware Forums that suggested that post I linked and I couldnt find anything else on it. The VMs I created were not from an older version of ESXi they were just recently built, about a month ago actually. ESXI 6.0 was installed several months ago.

VMware tool version 9.10.0 build 2476743

And it only seems to be the terminal servers. So I have more than one it is happening on but not on any other servers

I would escalate this to VMware Support, as this would suggest this bug as been re-introduced, and refer to the previous KB Article, and VMware Tools issue.

To test, you could revert to a previous version of VMware Tools, but this would be an unsupported configuration, so I would leave for VMware Support to experiment with, and check, and fix.

Took them a month to get back to me.

Hello xxx,
I apologize for the delayed response. We got fairly slammed the past week and took me some time to get back to this log reivew. I did verify that there are no immeiadte concerns in regards to the VMware Tools errors being displayed. However, I did find a few other cases with the customer having the same problem and upgraded to ESXi 6.0 U1 (VMware Tools version 9.10.5) and it seems to resolve the errors. It looks like there was a PR filed for this problem which spewed the warnings even though no impact was seen on the OS. I would recommend taking the following actions:

1) Ensure drivers/firmware/BIOS are up-to-date on the ESXi Host. Although this does not affect the VMware Tools per say, this will need to be done as the BIOS in particular is fairly out of date. Details on the current version are provided from the hardware vendor. You will want to verify this info with them on specifics.
Current: v1.1.4 | Date: 05/08/2009
New: Dell Inc. 6.4.0 UEFI Mode
bnx2 -
Current: driver = 2.2.4f.v60.10, firmware = bc 4.6.4 NCSI 1.0.6
New: driver = 2.2.5g.v55.2, firmware = 7.10.xx
2) Update ESXi to 6.0 Update 1a (ensure you patch to version U1a instead of the U1 only). Dell may have a custom ISO for this update but I am provide our base update below, in case it is needed.
Download VMware ESXi 6.0 U1a:

3) If you still see the problem, I would recommend implementing the following work around to suppress those errors. Let me know if you have any questions. This will be located in the "Resolution" section of the KB below.

With this information, I do not foresee any performance or usability impact to the virtual machine.
